[PATCH 7/8] [media] ttusb_dec: Add spaces for better code readability

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 13 Sep 2017 22:12:07 +0200

The script "checkpatch.pl" pointed information out like the following.

ERROR: spaces required around that '=' (ctx:VxV)

Thus fix the affected source code places.
